EDWARD H. AMET, OF PHOENIX, ARIZONA TERRITORY, ASSIGNOR TO INTERNATIONAL AMET COMPANY, OF PHOENIX, ARIZONA TERRITORY, A CORPORATION OF ARIZONA TERRI- TORY.

To all whom it may concern:

Be it known that 1, Enwano H. AME'r, a citizen of the United States. residing at Phoenix, in the county of Mar'icopa and 'lerritory of Arizona, have invented a new and useful Gas Cooler and Cleaner, of which thefollowing is a specification.

This invention relates to as coolers and cleaners adapted to cool an clean the as produced from hydrocarbon oils. It is silso adapted for cleaning other gases.

It is one of the objects of this invention to produce a compact, simple, cheap, economical, and eflicient means 'for cleaning and cooling gases, which will automatically cleanse itself and connections from the impurities removed from such gases and which will operate continuously with a minimum amount of water and attention, and in which provision is made for overcoming any back pressure that may be offered to the outgoing gases.

Other objects and advantages may appear in the matters followin I regard this invention as pioneer in a number of features. For instance, the details of the ap aratus bygwhich the gas is subjected to t e act-ion of-the' cleansing liquid, as water, while flowing downward,

so that the cleansing liquid and the gas move in the same general downward direction, and the motion of the liquid accelerates the motion of the gas. The tendency of the ure gaseous vIsubstance to gravitate, being ess than that of the solid or liquid particles inthe as, the force of gravity assists in the separatlon of thesolids and liquids from the gas, while the general downward direction of travel. is unchanged, and such separation occurs in a gentle and non-disruptive manner so as to avoid breaking up or disru ting any accumulation of solids which inay orm,

the tendency being always toward concen trating and separating the solids and liquids from the gas.

I employ the principle of successive accelerations and retardatio-ns of the gas while 1n intlmate combination with the cleansing liquid. The gas is'caused to travel at a cqmparatively veryhigh speed between the. subsidence contriva-nces sothat: when the gas (titers any such contriv-ance it comes into a con'iparatively quiescent condition, while the momentum ofv the solids tends to prO ect V the same onward through the gas in the di- Specification of Letters Patent.

rection the water tends to flow. At the same time provision is made whereby the course of the gas is frequently changed from a vertical to auchlique direction so that the force of gravity in the liquid and the solids will carry the same downward out of the course of the gas with which it "had been combined.

Obstacles are placed in the course of the gas and water in a stag ered arrangement'so that the solids may col ect on said obstacles, and provision is made for washing off the solids thus collected and carryin them out through traps at the bottom of t is a paratus. .The means for washing oft t e impurities may be of vari ous kinds, and in the accompanying drawings I shall illustrate the invention as applied in an apparatus in which a constant washing occurs in a. part of said apparatus, and an intermittent washing accomplished in another iart.

The invention may be applied in various forms, and I do not limit myseltto any particular form of construction.

I have discovered that deposits of byproducts from the gas as it comes from the generator or from the nerator-seal, will form more rapidly on a gfy plate or surface than on a wet plate or surface. For instance, if a. dry cloth be placed over the mouth of a pipe leading from the eneratorseal, the same will rapidly clog with soot or lamp-black, while if the cloth be kept wet, practically no accumulations of soot or lampblack will form. I have made provision for taking advantageof this fact in my present cooler and cleaner and have constructed the same in such manner that some of the surfaces arranged in the path of the gas will be a considerable portion of the time. so that the icy-products may readily adhere thereto, provision being made for intermittently removing the lay-products.

The tcndencyof the lay-products to separate from the as under the action of water is greater at he outset of the process of cleaning the gas than later on, and I have therefore made provision in the first portion of the washer for an uninterrupted flow of cleansing medium to deposit and wash away the Irv-products. and in the succeeding part of the washer l have made provision for practically dry plates which are intermittently washed with a cleansing medium to carry away the by-products which will into the top of whic deposit thereon washings.

The accompanying drawings illustrate the invention.

The nozzle 10 is air ranged to discharge a Jet of water along; the

. horlzontal pipe 6 toward the mouth. thereof betwecn the same, spaced apart. on

which is connected with the cylind'cr 7 .The purpose of this jet is two-fold; viz.,--tirst to accelcratc'thc mm ement of the gas) in-tlie gas-pipe (3, and second. to supply water to the top of the washer.

I 11 designates a. stack of disks 0t": sheet metal or o't.h er suitable material inside the cylinder ,7 to form a series of obstacles or impediments in the path'of the gas, the same being arranged one abo.ve the other with opeir'spirces between.

1-0 is a riser leading from the unit indicated at a upward to above the plane of the second unit Z1 and connected with said second unit by a horizontal pipe limb 1H.

19 and 2t) desigil'late two nozzles at the top of the riser 1.6. the nozzle I!) hein in the form of a sprinkler to spray the wa of the pi po 16 in the same manner as the sprinkler El sprays the walls ol the pipe 5. and the nozzle J0 being adapted to direct a jet of water along the l'lnl'lZUl'ilall pipe limb 18 in the name manner in which the nozzle 10 directs the water along the horizontal pipe t.

The interior construction of the unit I) corresponds to that of the unit a, and the like interior Jarts of these two units are des ip-natedday li ke characters.

"i1 is a riser 'connectcd with the lowest part of the cylinder 17 in the same manner as the riser it) is connected with the cylinder 7, and connected by pipe 22 with the cylinder 23 oi the. unit c.

designates a. nozzle to direct a. jet oi. water along the horizontal pipe 22 which ctnlllu'ls the top of the riser it with the top The several ctmnections (3,-lH. and 22 open downwardly into their respective cylinders at the axis thereof as indicated at The same is connected with cylinder 26 through riser 2i and connection 23'; and a nozzle 24 to spray and to accelerate the flow of gas in 22"and to (lush the pipe 22 and the unit. d.

side of the cylinders 23 and 26 in u nnuiner cm're-spomling to the disks 11 in the cyliudcrs 7 and 17, respectively, and each of these cylinders discharges the by products and the anslng liquid into the trough 4 through the pipes 13 which appertain thereto. I The disks 2'? of the units 1: and It are showinoi' a ditlercnt form l'roin the disks ll of the unlts u add I), the disks ll bcingiai the lorm oFiI star, the point of each of the .super msed stars heing'stay-gored relative to the points of the adjacent sta'rs, so as to form a'moro' or less tortuous putli InsHk-Qthocflits inder through which the gas must How, and

shown as perforatet with a.plu|'al-ity';t'iti holes, the pcrforatigni-s of one disk heing aborc'thc uu a-rl ornlod portion of. the disk In each of the units the as by the collars l t-.andflfl, thus forming hetwcon said disks'ekmmslon 't-.'l1:tI n la-rs,2tl into whneh the gas maylaecome distributed after through-the apertures of one. disk;

ratus, the purpose being to allow the stars 11 and disks 27 therein to be dry at the outset and at intervals thereafter during the operation of the apparatus so that after the gas has passed through. the units a and b and has deposited therein the more readily deposited by-products, it will come into contact with practically dry surfaces in the units and d, whereupon the by-products remaining" in the gas rapidly deposit u )OIl the disks or plates 27. After de osits 0 by-products are once formed on sai plates or disks, fur ther de )osits of the by-products ver readily form t ereon, the deposits alrear y made having an affinity for the by-prodncts car- 'ried by the gas. Each of the units 0 and d is provided with a flushing apparatus, the description of one of which will a ply to both. 30 is a flush tank; 31 a'valve watersupply-pipe; 32 an equalizing pipe between the gas pipe 22 and the top of the flushtank which is closed to the external air exceptthrough the apparatus.

33 is a flush ipe preferably of a smaller diameter than t 1e gas-pipe '22, the lower end of the same constituting the nozzle 24hereinbefore referred to, to direct a streanrof water along the pipe 22 in the direction in which the gas will flow from the pipe 21. Such stream of water is directed across the top of the pipe 21, so that some portion of,

water from the flushing stream as it flows across the top of pi )e 21 will break 11 011 the upper margin 0 the pipe 21 and low down such pipe for the purpose of wetting the walls thereof.

4 The flush-tank 30 is arranged at a considerable height, say five feet, more or less, above the top of the unit into which it discharges; the purpose being to provide a strong flushing stream so that when the flushing dischar c takes place the accumulations of by-products on the plates or diaphragms of the washer-unit will be washed off and down into the seal and'discharge trough 4.

The flush-pipe 33 may be provided'at its upper end wlth any desirable form of intermittent siphoning device, as indicated in a conventional way at 34, so that the tank 30 uilLfill to a determined depth, and thereupon will suddenly discharge through the flush-pipe 33 to Jerform the Work above described. Vhen t e liquid in the tank lowers sufliciently to admit air to the mouth of the siphon the How will cease, thus allowing the tank to again fill until siphoning flow is again established, whereu on the o oration just described is repeated Any esirable form of flashing device may be employed; for example, any of the well-known sewer man-hole flushing devices in common use, detail illustration of which is not here necessary.

The different parts of the flushing apparatus shown for the unit (Z are marked with characters corresponding to those with which like parts of the. apparatus for the unit 1: are marked, being distinguished therefrom by an index.

35 designates the gas outlet through the seal 30 and pipe 37 to the holder not shown, the seal 36 being provided with an overflow pipe 38 leading to the seal and discharge trough 4.

It is to be understood that. a greater or less number of washer units may be provided within the judgment of the constructor, and that all of the units a and J may be omitted; connecting the outlet with the pipe 21, or that the pipe 5 may be connected with the pipe 21 omitting the units a, I), and that the character of disks shown in units a and b may be employed in the units a and d, and vice versa; all of these changes being within the judgment of the constructor to meet the various requirements which he may find in any particular case, and I may change the construction of the apparatus in many rarious ways without de arting from the spirit of the invention whidh I have hereinbefore set forth and which is more 'particularly pointed out in the appended claims.

I deem the star form of disks shown in Fig. 3 as preferable to any other form for the purpose of affording a multitude of elongate edges fllfl illd which the gas may flow with consider-a le friction, so that the by-products will form on the edges and will break over and drop down from star-point to star-point while the gas is divided into a n'rultiplicity of streams and is forced to take a tortuous course between the points of one star and those of the succeeding star, spreading out in all directions in the interposed chambers which form expansions of the gas way between the interstices of the individual stars, and which interstices form contractions of said way, so that the as is alternately expanded and contracted as it passes through the interstices and the intermediate chambers. At intervals in the stacks of washer disks or stars 1.1, other disks, as 40, are provided, having blades 41 set aslant'to direct the gas around in the chamber below,

thus to give a circular motion to the gas as it passes through the washer.
